Comment #3 on issue 4168 by [email protected]: Array.of/from
use %AddElement unsafely
https://code.google.com/p/v8/issues/detail?id=4168
Oh, I see:
d8> function y() { Object.defineProperty(this, '0', {value: 1,
configurable: false, writable: false}); }
undefined
d8> Array.of.call(y, [5])
{0: 1, length: 1}
Spec-wise, we're supposed to throw since CreateDataProperty returned false.
However, we silently swallow the error. This isn't a safety issue though.
But I'm still reading the code...
